VALVE.

Specification of Letters Patent.

Patented May 21', 1907.

Application filed August 15,1906. Serial No. 330,662.

To all whom it may. concern:

Be it known that I, JAooB WEBER, asubj ect of the Emperor of Germany,and a resident of Chelsea, in the county of Suflolk and State ofMassachusetts, have invented new and useful Improvements in Valves, ofwhich the following is a specification.

My invention is a new article of manufacture and is designed especiallyforuse as a valve in a tap or faucet forcasks of ale and the like, butit obviously may be used for other purposes.

As is well known, kegs, casks and the like,

I such as are usedby brewers of ale and beer,

are made with a tap hole in the head and stave through which the packagemay be filled by the brewer and through which its contents are drawn offby the consumer. It has been customary to fix a valve in the tap holewhich could be used by the brewer in filling the package and by theconsumer to control the discharge of the contents of the package.Ordinarily this valve has been made up of a body eXterlorly threaded andscrewed into the tap hole, a rotary slide or gate valve at the inner endof the body and within the package and a stem extending from the valvethrough the valve body. to the exterior of the package, the outer end ofwhich stem was adapted to be engaged by a detachable faucet wrenchthrough turning which the stem could be rotated and the valve opened.

It is customary in the use of ale casks and the like to coat theinterior of the cask at intervals with hot pitch. It is obvious that inany valve in which there are openings openin to the interior of thecask, the liquid pitch wi l or may enter the openings and so cement theparts of the valve together that it may be impossible thereafter tooperate the valve unless very great force is used which may result inbreaking the parts of the valve, and in any event the pitch may getbetween the opposed faces and score or pit them so that the valve willnot be either liquid or gas tight which it is essential that the valveshould be.

My improved valve is designed to present to theinterior of the cask apractically continuous surface and in its opening and closing to have apeculiar movement compounded of a rotary movement and a horizontalmovement so that the pitch deposited upon the surface of the valvecasingwithin the cask is easily broken along the junction line of thetwo parts of the valve and designed to-be moved positively both in itsopening movement and in its closing movement without any use whatever ofsprings and to be securely locked both in its open position and 1' inits closed position.

In the accompanying drawings,Figure 1 is a side elevation of my valve inits closed position; Fig. 2 is a vertical section of Fig. 1 in the sameplane showing the valve in its open position; Fig. 3 is a section on theline 33 of Fig. 4; Fig. 4 shows the interior of the valve casing; Fig. 5is a perspective of the valve stem and crown cams; and Fig. 6 is adiagrammatic view showing a development of the wing cam and adjacentmembers of the casing.

In my improved valve the valve body A is a hollow shell exteriorlythreaded asusual and closed at its inner end by a wall a in which areports a and a passa e a. for the valve stem. Upon the face of t 's endWall 0. within the body A are two cam surfaces B, and upon the interiorside walls of body A are two cam lugs or projections C. The valve stem Dcarries 'near its outer end two Wings (1, these wings carrying upon boththe upper surface and the under surface properly shaped cam surfaces (1d which co-operate respectively with the cam surfaces B'upon the outersurface of the end wall and the cam lugs C disposed upon the insidewalls of the body. The outer end (1 of this valve stem is of angularsection to receive a socketwrench, which is usually formed upon theinner end of the removable faucet, by means of which the valve stem maybe turned. The valve stem is passed through the aperture provided in theinner wal of the body, the cam lugs C upon the inside alls of the bodypassing between the ends of the two ;wings to ermit the two wings topass below them and between the cam lugs C on the side wall and the camsurface B upon the inside of the end wall. When so positioned the camsupon the upper and the under surface of the wings are in position toco-operate with the cam surfaces upon the inner side of the end wall andthe cam surfaces on the lugs disposed upon the inside wall of the body.The valve stem projecting through the inner wall as aforeperiphery ofthe face opposed to the inner end of the valve body, a beveled valveface, which co-operates with a corresponding face upon the end'of thevalve body. The diameter of this disk is equal to the diameter of thevalve body, and the valve faces are accurately fitted, so that when thevalve is closed there is hardly an indication of the joint. Within theconical valve seat is a recess w the purpose of which is to receive andhold harmlessly any particles of pitch that may find their way onto orthrough the valve seats.

The cam surfaces upon the body and upon the valve stem wings are sodisposed, as shown in the drawin s, that a .quarter turn of the valvestem wi 1 cause the valve stem to be moved inwardly to open the valve,if it be closed or outwardly to close it if it be open, the stem andvalve, during the movement longitudinal of the axis turning one quarterturn, so that a oint upon the periphery of the valve wili move in ahelical path. At the end of each, movement the cams ride upon flatsurfaces so that the stem and valve are locked against any movementendwise and can only be moved, by rotating the stem to reverse theposition of the valve.

The locking action of the parts when the valve is open is clearly shownin Fig. 6. When the cam projection (1 passes into the recess, one sideof which is cam B, the flat upper surface of the cam projection 11 isbeneath the lug C so that direct longitudinal movement of the stem isprevented. When the stem is turned the cam d rides up cam B until theflat surface as is upon the inner surface of wall a, thus locking thestem against longitudinal movement until it is again turned to cause thecam d to enga e lug O and cam. d to ride down cam B, w en the having camwings the upper surface of which co-operates with one abutment and thelower surface with another abutment to cause the stem to be firstrotated and then moved longitudinally as it is rotated, the inner end ofthe stem passing throu h the wall of the body and carrying a valve pate; that valve plate, adapted, by the rotating-longitudinal movement ofthe valve stem to be moved a ainst or away from the inner wall of thebody.

2. As a new article of manufacture, the valve, made up of a hollow bodyportion, having a perforate wall, abutments upon the inside of the body;a stem having wings carrying cam surfaces upon the upper and lowersurfaces thereof, the cams being opposed in action and co-operating withthe abutments upon the inside of the body to actuate the stemlongitudinally and lock it in its extreme positions, the inner end ofthe stem projectmg through the end wall of the body and carrying a valvefast thereto, all organized to hold the valve against or away from theinner wall of the body.

3. As a new article of manufacture, the valve, made up of a hollow bodyportion, having a perforate wall; abutments upon the inside of the body;a stem having cam Wings .the upper surface of which co-operates with oneabutment and the lower surface with another abutment to cause the stemto be moved longitudinally as it is rotated, the inner end of the stempassing through the wall of the body and carrying a valve plate; corripcry of the valve plate and body and a recessed portion within the plateseat, substantially as described.
